volutin[′väl·yəd·ən] (biochemistry) A basophilic substance, thought to be a nucleic acid, occurring as granules in the cytoplasm and vacuoles of algae and other microorganisms. Volutin intracellular inclusions in microorganisms; a temporary reserve of nutrients similar to fatty inclusions and glycogen granules in animals. Volutin is localized in the cytoplasm (in bacteria and actinomycetes) or in vacuoles (in fungi and algae). Volutin is strained by basic dyes. It is usually composed of high-molecular polyphosphates and less commonly of poly-β-hydroxybutyric acid or other compounds. volutin
